I'm pretty sure some form of meth was used by kamikazes in WW2 to make it easier to completethe task. All though that was Japan, I'm almost certain Japan and China are pretty close geographically.So don't go patting yourself on the back USA.

I've heard that meth is quite popular in Japan, the Yakuza's single biggest source of income even. It's popular in parts of SE Asia, too, especially with prostitutes. It would be strange if the Chinese stayed out out of this line of work entirely; after all, there's money to be made.
